Rusted Cast Iron Crank Handle Component

This item appears to be a component of a crank handle, likely made from cast iron, given its rough texture and significant oxidation. The main body of the item is L-shaped with a circular opening at one end, which accommodates a bolt and nut assembly, suggesting it once rotated around an axle or shaft. The primary color is a deep reddish-brown, indicative of severe rust covering the entire surface. The construction is robust and monolithic, consistent with a cast manufacturing process designed for strength and durability. "DSC" is cast in raised lettering on the flat section of the L-shape, which likely denotes a manufacturer's mark, model number, or perhaps a part designation. The bolt and nut at the circular end are also heavily rusted and appear to be original or long-attached fasteners, further integrating into the overall age and condition of the piece. There are no obvious signs of repair, but the extensive surface rust represents a significant condition issue, obscuring finer details and potentially compromising the material's integrity. The item exhibits an aged patina characteristic of prolonged exposure to the elements. Given its robust construction and heavy rust, it likely belongs to an older piece of machinery or equipment, possibly from the mid-20th century or earlier. Its function was almost certainly to provide leverage for turning, implying use in industrial, agricultural, or heavy-duty mechanical applications. The craftsmanship, though basic, suggests a utilitarian design built for function rather than aesthetics.
